Befaco Rampage

The Befaco Rampage is an effects module for synthesizers in Eurorack format. The module is based on the dual function generators developed by Serge and Buchla. It consists of 2x voltage-controlled integrators. Integrators (also known as lag processors or slew limiters) make it possible to process voltages and convert sharp square waves into ramp-shaped waveforms. The module contains two function generators with an additional analog logic processor and a slope detector for each function generator.

Fields of ApplicationThe Rampage can be used in many different ways, making it the perfect multi-purpose tool. The module can be used as an ASR or complex ADSR envelope, dual VCO with square wave, sawtooth, triangle wave and PWM and logarithmic and exponential waves, dual low-pass filters with and without VCO Soft Sync and LFO with square wave, sawtooth and triangle waveform. Further applications are also possible, such as a polyrhythmic gate generator, dual slope detector, slew limiter or envelope follower.
